How Our Roofing Work Looks Once the Job Is Done
Roofing Contractor Lansdowne, PA
Protect Older Rooflines Before Leaks Travel
Roofing Built for Lansdowne's Historic Homes & Tight Borough Lots
Lansdowne is a borough of old roofs. Queen Anne Victorians, Foursquares, Tudors, and Cape Cods line the streets, most built between the 1890s and the 1940s, many with slate, steep gables, turrets, dormers, and deep front porches. William Penn Roofing has been the roofing contractor for these blocks since 2008, and we know the rooflines: where a century-old slate roof can still be saved, where a porch roof is quietly letting water in, and how to work a narrow borough lot without harming the home attached to yours.
Owners here usually arrive with one question, repair or replace, and on an older Lansdowne home the answer is worth real money. We give it to you straight, off an honest inspection instead of a sales script.

Roofing for Slate, Shingle, Porch & Low-Slope Roof Sections
A Lansdowne home often carries more than one kind of roof at once. The main roof might be slate or asphalt over a steep gable, while the porch and rear additions run low-slope, and each meets the others at valleys, dormers, and flashing lines that are the usual leak points.
- Slate and specialty roofs: we repair, match, and replace slate, copper, and decorative shingle work rather than tearing off a roof that still has decades left in it.
- Porch and low-slope sections: near-flat porch roofs do not shed water well, so we re-flash, re-seal, or re-membrane them before the leak reaches the ceiling below.
- Valleys, dormers, and turrets: the details that give these homes their character are also where water finds a way in, and where careful flashing work matters most.
These are the roofs we handle every week across the borough and just over the line in Drexel Hill, where the housing stock is much the same age.
Residential Roofing Services That Respect the Whole System
A roof is a system: slate or shingle, underlayment, flashing, ventilation, and drainage all working together. When one part fails, the leak often shows up far from the cause. Our residential roofing services start by finding that cause, then fixing it so the repair lasts.
Roof Inspection & Leak Diagnosis
We inspect the full roof, slate and shingle fields, porch and low-slope sections, flashing, valleys, and ventilation, then hand you photos of anything we find along with a clear scope of work.
Roof Repair
We repair slipped slate, cracked shingles, failed flashing, porch-roof leaks, and the valley and dormer details where older roofs tend to give out first.
Roof Replacement & New Roof Installation
When a roof is truly past its life, we install a full system with new underlayment, ice and water shield, flashing, and a slate, shingle, or membrane matched to each section's slope.
Storm Damage Repair & Emergency Tarping
After a storm we start with an emergency tarp and dry-in, then a permanent storm damage repair, photographing the damage for your insurance claim. Tall, steep Victorian roofs and mature street trees mean a storm here can do real damage fast.
How to Tell If Your Roof Needs Professional Attention
Watch for these before the next storm; any one of them is reason to call:
- Slipped, cracked, or missing slate or shingles
- Water stains on ceilings, around chimneys, or over the porch
- Sagging or soft spots on a porch or low-slope section
- Granule loss collecting in the gutters
- Daylight, damp, or mold in the attic
- Flashing pulling away at valleys, dormers, or walls
Plan Your Roofing Costs Before Scheduling Work
No two Lansdowne roofs cost the same. A slate roof runs more than asphalt, a steep multi-level Victorian takes longer, porch and low-slope sections add flashing work, and a narrow borough lot can complicate access.
Commercial & Flat Roofing for Lansdowne Properties
Lansdowne’s business district along Lansdowne and Baltimore Avenues runs on storefronts, mixed-use buildings, and converted multi-unit properties, most with flat or low-slope roofs. We keep those flat roofs going with commercial roofing across TPO, EPDM, modified bitumen, and coatings, for owners in the borough and along the Springfield retail corridor.
Commercial Roof Repair
Ponding, open seams, and worn membrane on a flat roof get focused repairs that add years before a replacement is due.
Commercial Roof Replacement
When a flat roof is no longer worth patching, we replace it with a membrane matched to the building's drainage and use.
Commercial Roof Coating
A reflective coat can extend a sound flat roof and ease summer cooling costs. If it is a fit we will say so, and if the roof is spent we will tell you that instead.
Our Roofing Process From Diagnosis to Final Review
Every project follows the same roadmap, so you always know what is happening and what comes next.
Roofing Materials for Character, Durability & Weather Resistance
On a historic Lansdowne home, the right material protects the house and keeps its character. Our work covers pitched, specialty, and flat systems.
Asphalt Shingles
A cost-effective, reliable choice for pitched roofs, with looks that can complement an older home.
Metal Roofing
Long-lasting and wind-resistant, a fit for some homes and low-slope sections.
Cedar Roofing
Natural cedar shingles that suit the Shingle Style and Victorian homes Lansdowne is known for.
Copper Roofing
A premium accent for turrets, bays, and porch roofs that ages into a classic patina.
Slate Roofing
The signature roof of Lansdowne’s Victorians, repaired, matched, or replaced to keep the home’s historic look.
TPO Flat Roofing
A reflective, energy-conscious membrane for flat porch, addition, and commercial roofs.
EPDM Rubber Roofing
A flexible rubber membrane well suited to low-slope porch and rear sections.
Modified Bitumen Roofing
A layered, durable system for flat commercial and multi-unit roofs.
Exterior Services That Help Keep Water Out
A roof depends on everything around it staying watertight. When a project turns up a related problem, we can take on the connected exterior work as well.
Gutter Replacement
New gutters and replacement to carry water off the roof and away from the porch, walls, and foundation.
Siding Replacement
Siding replacement for the spots where moisture has worked in behind a tired exterior.
Skylight Installation
Skylight installation set in with proper flashing and sealing, so the light comes in and the water stays out.
Stucco Remediation
Stucco remediation for the cracked or moisture-trapped stucco common on older homes.
Window & Door Installation
Window and door installation to replace old units that let in drafts and rain.
Installed With Reliable Roofing & Exterior Brands
The slate, shingle, and membrane we put on a Lansdowne roof come from GAF, Owens Corning, CertainTeed, Velux, and James Hardie, installed to each maker’s spec so the warranty stands behind the work.
Why William Penn Roofing Is the Team Owners Recommend
Our edge is in how we handle older roofs. Plenty of contractors look at a slate Victorian or a leaking porch and quote a full tear-off; owner David looks for what can actually be repaired and tells you straight, because on a historic Lansdowne home that call can be worth thousands of dollars.
The owner inspects it himself. David gets up on the roof in person, so your estimate comes from the one who actually looked at the slate and flashing, not a rep on commission.
Comfortable on slate and steep Victorian roofs. Slate, copper, turrets, and dormers are work many roofers avoid; for us it is routine, and we repair before we replace.
Careful on tight lots and twin homes. We protect the porch, the plantings, and the home attached to yours, and clean up completely where there is no room to spare.
What Lansdowne Owners and Landlords Ask Us Most
How long does a slate roof last on a Lansdowne Victorian?
A well-maintained slate roof can last 75 to 100 years, far longer than asphalt. Often the slate is fine and only the flashing or a few slipped tiles need attention, which is why we inspect before recommending replacement.
Can you repair or replace a roof on a tight borough lot?
Yes. Most Lansdowne lots are narrow with little room for equipment, so we plan material and dumpster placement and protect the neighboring home so the work fits the space.
Do you work with landlords and multi-unit owners in Lansdowne?
Yes. Many borough homes are twins, triplexes, and converted apartments, and we handle rentals and multi-unit roofs for landlords with quick turnarounds between tenants.
Can you inspect a roof before I buy or sell a home in Lansdowne?
Yes. We provide pre-purchase and pre-sale roof inspections with photos and a written summary, so buyers and sellers know exactly what the roof needs.
Are you licensed and insured to work in Lansdowne?
Yes. William Penn Roofing is a licensed and insured Pennsylvania contractor, PA HIC #064688, taking on residential and commercial roofs throughout Lansdowne and the rest of Delaware County.
Fix the Weak Spot Before the Next Rain Finds It
A roof problem does not wait for a convenient time. A slipped slate or an open porch-roof seam becomes a stained ceiling and a bigger bill the next hard rain. Have us take an honest look and tell you what the roof actually needs, and what it does not.
